[0003] This application provides a heat exchanger end plate, a heat exchanger assembly, and an air conditioner, which can eliminate electrical safety hazards and dripping noise, and ensure the safe and quiet operation of the air conditioner.

[0004] In a first aspect, embodiments of this application provide a heat exchanger end plate for installation on one end of a heat exchanger along a first direction. The heat exchanger end plate is provided with a plurality of flanged through-holes and at least one first guide rib. The plurality of flanged through-holes are spaced apart, and the flanges of the flanged through-holes are formed on the side surface of the heat exchanger end plate away from the heat exchanger. The flanges of two adjacent flanged through-holes are connected by the first guide rib. The first direction is the length direction of the heat exchanger.

[0005] In some embodiments, at least one of the tops of the first guide rib is recessed along the first direction to form a first flow outlet.

[0006] In some embodiments, the top of the flange of at least one of the flanged through-holes is recessed along the first direction to form a second flow port.

[0007] In some embodiments, the heat exchanger end plate has a heat exchanger connection portion and a heat exchanger clearance portion. The heat exchanger connection portion is disposed around the heat exchanger clearance portion and located on the upper side of the heat exchanger clearance portion. The plurality of flanged through-holes and the at least one first guide rib are disposed within the heat exchanger connection portion. A guide slope is formed on the side of the heat exchanger clearance portion facing the heat exchanger connection portion, and the guide slope is located on the lower side of the plurality of flanged through-holes.

[0008] In some embodiments, the heat exchanger clearance portion is provided with at least one second guide rib, the second guide rib is connected to the area on the heat exchanger clearance portion where the guide slope is provided, and the second guide rib extends downward.

[0009] In some embodiments, the heat exchanger clearance portion protrudes from the side surface of the heat exchanger end plate away from the heat exchanger, the top of the heat exchanger clearance portion is recessed to form a recess, and the second guide rib is disposed in the recess to divide the recess into a plurality of grooves; the heat exchanger clearance portion is provided with a plurality of second guide ribs, and the plurality of second guide ribs are arranged sequentially at intervals along the extension direction of the guide slope.

[0010] In some embodiments, the heat exchanger has a U-shaped tube section, and the flanged through-hole is a waist-shaped flanged hole, which is adapted to pass through the U-shaped tube section.

[0011] In some embodiments, a protective fold is provided on the side surface of the heat exchanger end plate facing the heat exchanger; when the heat exchanger end plate and the heat exchanger are connected, the protective fold wraps around the end of the heat exchanger.

[0012] In some embodiments, the bottom of the heat exchanger end plate is provided with a window portion, which extends through the heat exchanger end plate in a vertical direction; when a water receiving tray is provided on the lower side of the heat exchanger end plate, the window portion and the drain nozzle of the water receiving tray are correspondingly provided.

[0013] Secondly, embodiments of this application provide a heat exchanger assembly, including a heat exchanger and a heat exchanger end plate as described in any of the above embodiments, wherein the heat exchanger end plate is mounted on one end of the heat exchanger along the first direction.

[0014] Thirdly, embodiments of this application provide an air conditioner including the heat exchanger assembly described in the above embodiments.

[0015] This embodiment of the application provides a first guide rib on the heat exchanger end plate that connects the flanges of two adjacent flanged pipe holes. When condensate is generated in the heat exchanger tubes, the condensate can flow onto the flange of the flanged pipe hole and, driven by its own weight, flow directionally towards the flange of the lower flanged pipe hole through the first guide rib. This allows the condensate to flow layer by layer along the first guide rib to the flange of the lowest flanged pipe hole, and finally drip into the water collection tray located below the heat exchanger end plate. In this way, the dripping height of the condensate from the heat exchanger to the water collection tray can be reduced. On the one hand, this avoids the condensate from dripping from a height and splashing onto adjacent electronic components, eliminating electrical safety hazards. On the other hand, it avoids the obvious dripping impact sound caused by the condensate dripping from a height, eliminating dripping noise, thereby ensuring the safety and quiet operation of the air conditioner.

The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0028] like Figure 1 and Figure 2 As shown, in a first aspect, this application provides a heat exchanger end plate 1, which is used to install on one end of the heat exchanger 2 along a first direction. This can eliminate electrical safety hazards and dripping noise, and ensure the safe and quiet operation of the air conditioner.

[0029] Here, the heat exchanger end plate 1 is provided with a plurality of flanged tube through holes 11 and at least one first guide rib 12. The plurality of flanged tube through holes 11 are spaced apart, and the flanges 111 of the flanged tube through holes 11 are formed on the surface of the heat exchanger end plate 1 away from the heat exchanger 2. The flanged tube through holes 11 are used to pass through the heat exchange tubes of the heat exchanger 2, so that the heat exchanger end plate 1 is positioned at the end of the heat exchanger 2. The flanges 111 of two adjacent flanged tube through holes 11 are connected by the first guide rib 12, which guides the condensate to flow directionally between the two adjacent flanged tube through holes 11. The first direction mentioned above refers to the length direction of the heat exchanger 2.

[0030] Compared with related technologies, the heat exchanger end plate 1 provided in this application embodiment is installed at the end of the heat exchanger 2. When condensate is generated in the heat exchange tube of the heat exchanger 2, the condensate can flow to the flange 111 of the flanged through-hole 11 and, driven by its own weight, flow directionally to the flange 111 of the flanged through-hole 11 located on the lower side through the first guide rib 12. This allows the condensate to flow layer by layer along the first guide rib 12 to the flange 111 of the flanged through-hole 11 located on the lowest side, and finally drip into the water receiving tray 3 located below the heat exchanger end plate 1. In this way, the dripping height of the condensate from the heat exchanger 2 to the water receiving tray 3 can be reduced. On the one hand, this avoids the condensate from dripping from a height and splashing onto adjacent electronic components, eliminating electrical safety hazards. On the other hand, it avoids the condensate from dripping from a height and producing obvious dripping impact sound, eliminating dripping noise, thereby ensuring the safety and quiet operation of the air conditioner.

[0031] In some embodiments, the top of at least one first guide rib 12 may be recessed along a first direction to form a first flow outlet 121. In some examples, only the top of some of the first guide ribs 12 may be recessed along the first direction to form a first flow outlet 121, while the tops of the remaining first guide ribs 12 are not provided with a first flow outlet 121; in other examples, the top of each first guide rib 12 may be recessed along the first direction to form a first flow outlet 121. By providing the first flow outlet 121, during the process of guiding the condensate along the first guide rib 12, the condensate can pass through the first guide rib 12 through the first flow outlet 121 under its own weight and flow downward, so that the condensate gradually flows downward and converges, increasing the guiding effect.

[0032] In some embodiments, the top of the flange 111 of at least one flanged through-hole 11 can be recessed along a first direction to form a second flow port 112. In some examples, only the top of the flange 111 of some flanged through-holes 11 can be recessed along a second direction to form a second flow port 112, while the top of the flange 111 of the remaining flanged through-holes 11 does not have a second flow port 112; in other examples, the top of the flange 111 of each flanged through-hole 11 can be recessed along a second direction to form a second flow port 112. By providing the second flow port 112, during the process of guiding condensate along the flange 111 of the flanged through-hole 11, it can pass through the second flow port 112 under its own weight and flow downward, so that the condensate gradually flows downward and converges, increasing the guiding effect.

[0033] In some embodiments, the heat exchanger end plate 1 may have a heat exchanger connection portion 13 and a heat exchanger clearance portion 14. The heat exchanger connection portion 13 is disposed around the heat exchanger clearance portion 14 and is located on the upper side of the heat exchanger clearance portion 14. The heat exchanger connection portion 13 is used to connect and fix with the heat exchanger 2, and a plurality of flanged through holes 11 and at least one first guide rib 12 are respectively disposed in the heat exchanger connection portion 13. The heat exchanger clearance portion 14 is disposed to avoid the heat exchanger 2, and a guide slope 141 is formed on the side of the heat exchanger clearance portion 14 facing the heat exchanger connection portion 13; the guide slope 141 is located on the lower side of the plurality of flanged through holes 11 to guide the condensate flowing from the flanged through holes 11 and the first guide rib 12 in the heat exchanger connection portion 13 to the guide slope 141, so that the condensate flows slowly and horizontally into the water receiving tray 3 located below the heat exchanger end plate 1. By providing a heat exchanger clearance section 14, the flow can be guided between the heat exchanger connection section 13 and the water receiving pan 3, preventing condensate from dripping rapidly from a height and causing splashing and dripping noise.

[0034] In some examples, at least one second guide rib 142 may be provided on the heat exchanger clearance portion 14. The second guide rib 142 is connected to the area on the heat exchanger clearance portion 14 where the guide slope 141 is provided, and the second guide rib 142 extends downward. By providing the second guide rib 142, when a large amount of condensate collects on the guide slope 141, the second guide rib 142 can be used to gently guide the condensate horizontally to the water receiving tray 3 located below the heat exchanger end plate 1; in this way, the guide slope 141 and the second guide rib 142 can guide the condensate separately, avoiding the rapid dripping of condensate from a height, which would cause splashing and dripping noise.

[0035] The forming method of the heat exchanger clearance portion 14 can be determined according to actual needs, and this application embodiment does not limit it. For example, the heat exchanger clearance portion 14 can be formed protrudingly on the surface of the heat exchanger end plate 1 away from the heat exchanger 2, for example, by stamping, so that the heat exchanger clearance portion 14 protrudes beyond the surface of the heat exchanger connection portion 13. The top of the heat exchanger clearance portion 14 can be recessed to form a recess, and the second guide rib 142 is disposed in the recess to divide the recess into multiple grooves 143. For example, the heat exchanger clearance portion 14 is provided with multiple second guide ribs 142, which are sequentially spaced along the extending direction of the guide slope 141.

[0036] For example, the protrusion height of the second guide rib 142 can gradually increase from top to bottom along its extension direction, so that the top surface of the second guide rib 142 forms a guide surface that extends downward at an incline, so as to gently guide the condensate horizontally to the water receiving pan 3 located below the heat exchanger end plate 1, thereby avoiding the condensate from dripping rapidly from a height and causing splashing and dripping noise.

[0037] The structure of the heat exchange tube can be determined according to actual needs, and this application embodiment does not limit it. In some embodiments, the heat exchanger 2 may have a U-shaped tube section, that is, the heat exchange tube has a U-shaped tube section, and the flanged tube hole 11 can be a waist-shaped flanged hole, which is suitable for inserting the U-shaped tube section.

[0038] like Figure 3 As shown, in some embodiments, a protective flange 15 may be provided on the surface of the heat exchanger end plate 1 facing the heat exchanger 2. When the heat exchanger end plate 1 and the heat exchanger 2 are connected, the protective flange 15 wraps around the end of the heat exchanger 2. In this way, the protective flange 15 can shield and protect the sharp parts of the end of the heat exchanger 2, such as fins, to prevent operators or other objects from being scratched by the sharp parts.

[0039] like Figures 1 to 4 As shown, in some embodiments, the bottom of the heat exchanger end plate 1 may be provided with a window 16, which extends vertically through the heat exchanger end plate 1. When a water receiving tray 3 is provided on the lower side of the heat exchanger end plate 1, the window 16 and the drain nozzle of the water receiving tray 3 are correspondingly arranged. In this way, it is possible to observe whether the drain nozzle of the water receiving tray 3 is blocked through the window 16, and if the drain nozzle is blocked, it can be cleared through the window 16 to restore the drainage. During this process, it is not necessary to disassemble the entire equipment where the heat exchanger 2 is located, thus improving the convenience of maintenance.

[0040] Secondly, embodiments of this application provide a heat exchanger assembly. This heat exchanger assembly includes a heat exchanger 2 and a heat exchanger end plate 1 as described in any of the above embodiments, the heat exchanger end plate 1 being mounted on one end of the heat exchanger 2 along a first direction. The heat exchanger assembly provided in this application, having the aforementioned heat exchanger end plate 1, can eliminate electrical safety hazards and dripping noise, ensuring the safe and quiet operation of the air conditioner.

[0041] In some embodiments, the heat exchanger assembly may include two heat exchanger end plates 1, which are respectively mounted on opposite ends of the heat exchanger 2 along a first direction.

[0042] Thirdly, this application provides an air conditioner that includes the heat exchanger assembly described above. The type of air conditioner can be determined according to actual needs, and may include, for example, a wall-mounted air conditioner, a floor-standing air conditioner, or a ceiling-mounted unit; this application does not limit this type. The heat exchanger assembly provided in this application, having the aforementioned components, can eliminate electrical safety hazards and dripping noise, ensuring the safe and quiet operation of the air conditioner.

[0043] The heat exchanger end plate, heat exchanger assembly, and air conditioner provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
